The kind where if you have to be around people you feel more comfortable in a group than with just one other person?
I get nervous around "dead air" if I'm with people so if I'm the only other person I feel pressure to be interesting and it's exhausting. If there's a group of people it's not so bad because it divides the responsibility of being entertaining around all of us so I don't have to worry if I'm boring. I can just chill and let other people talk.
Plus I find I'm better at bouncing off of others than initiating conversation.
I think finding a place of comfortable silence is one of the nicest things about having a love affair but its also not an unreasonable expectation of your close friends, who I feel should not expect constant entertainment from you. But yeah it is a constant struggle against that dynamic in uncertain social circumstances, 1-on-1 can be a nightmare
